Tropical storms are likely to become more deadly under climate change, leaving people in developing countries, where there may be a lack of resources or poor infrastructure, at increased risk, new research shows.

Heart attack, or myocardial infarction, is the number one cause of death worldwide. A new study shows that the risk of suffering a heat-induced heart attack has increased significantly in recent years. During the same period of time, no comparable changes in cold weather heart attack risks have been recorded.

Modern coal-fired power stations produce more ultrafine dust particles than road traffic and can even modify and redistribute rainfall patterns, a new 15-year international study shows. The study indicates filtration systems on modern coal-fired power stations are the biggest source of ultrafine particles and can have considerable impacts on climate in several ways.

Rainy weather is becoming increasingly common over parts of the Greenland ice sheet, triggering sudden melting events that are eating at the ice and priming the surface for more widespread future melting, says a new study. Some parts of the ice sheet are even receiving rain in winter -- a phenomenon that will spread as climate continues to warm, say the researchers.

Temperatures may climb and seas may rise, but the lights (and, undoubtedly, the air conditioning) will still be on in nations with high capacities for wind and solar energy. New research suggests that these electricity systems should work almost equally well in both historical and future European climates despite changing weather patterns.

A new drought monitoring method allows scientists to identify the onset of drought sooner, meaning conservation or remediation measures could be put into place sooner. The new method uses thermal stress -- the difference between air and surface temperatures at a site -- as a drought indicator.

What kinds of weather do people find remarkable, when does that change, and what does that say about the public's perception of climate change? A study examined those questions through the lens of more than 2 billion US Twitter posts.

With average precipitation of 35 inches per four-month season over an area encompassing most of the Indian subcontinent, the South Asia summer monsoon is intense, only partly understood, and notoriously difficult to predict. Until now.

Climate change is shifting the energy in the atmosphere that fuels summertime weather, which may lead to stronger thunderstorms and more stagnant conditions for midlatitude regions of the Northern Hemisphere, including North America, Europe, and Asia, a new study finds.

The weather these days is wild and will be wilder still within a century -- in part, because the water from melting ice sheets off Greenland and in the Antarctic will cause extreme weather and unpredictable temperatures around the globe. A new study is the first to simulate the effects, under current climate policies, that the two melting ice sheets will have on ocean temperatures and circulation patterns as well as on air temperatures by the year 2100.

The forecast for the global average surface temperature for the five-year period to 2023 is predicted to be near or above 1.0 degree C above pre-industrial levels, says the United Kingdom's Met Office. If the observations for the next five years track the forecast, that would make the decade from 2014 to 2023 the warmest run of years since records began.

Researchers sought to understand how climate change, specifically changes in snowpack and VPD, is affecting pikas. Researchers related population abundances to weather and snowpack dynamics in the North Cascades National Park Service Complex in Washington state.

Climate change is causing significant changes to phytoplankton in the world's oceans, and a new study finds that over the coming decades these changes will affect the ocean's color, intensifying its blue regions and its green ones. Satellites should detect these changes in hue, providing early warning of wide-scale changes to marine ecosystems.

The 4,300 kilometer Mekong River is a lifeline for South-East Asia. If this mighty river system bursts its banks, flooding can affect the lives and livelihoods of millions of people. A new method makes it possible to monitor complex river basins using satellite data only.

Corn is planted on approximately 90 million acres across the United States every year. With all that data, it takes months after harvest for government agencies to analyze total yield and grain quality. Scientists are working to shorten that timeline, making predictions for end-of-season yield by mid-season. However, fewer researchers have tackled predictions of grain quality, especially on large scales. A new study starts to fill that gap.

Global food production is suffering from an increasing number of 'food shocks,' with most caused by extreme weather and geopolitical crises. An international study looked at the incidence of land and marine food shocks -- sudden losses in food production -- between 1961 and 2013.

Even though climate change is expected to reduce the total amount of US snowfall this century, it's unlikely to significantly rein in the most powerful nor'easters that pummel the East Coast, new research indicates.

Greenland is melting faster than scientists previously thought -- and will likely lead to faster sea level rise -- thanks to the continued, accelerating warming of the Earth's atmosphere, a new study has found.

Heat trapped by greenhouse gases is raising ocean temperatures faster than previously thought, concludes an analysis of four recent ocean heating observations. The results provide further evidence that earlier claims of a slowdown or 'hiatus' in global warming over the past 15 years were unfounded.

How does one inspect solar panels in real time, in a way that is both cost-effective and time-efficient? Researchers have now developed and improved statistical and machine learning-based alternatives to enable real-time inspection of solar panels. Their research found a new application for clustering-based computation, which uses past meteorological data to compute performance ratios and degradation rates.

A new study combining data from citizen scientists and weather radar stations is providing detailed insights into spring bird migration along the Gulf of Mexico and how these journeys may be affected by climate change. Findings on the timing, location, and intensity of these bird movements have been published.

The mass death of flying foxes in extreme heat in North Queensland last month underscores the importance of wildlife research released today. The new research sheds light on how various species have responded to major climate events.

In order to analyse climate change or provide information about natural hazards, it is important to gather knowledge about the rain. Better knowledge of precipitation and its distribution could, for example, help protect against river flooding. A new approach uses, for the first time, information contained in radar signals from navigation satellites to detect rain over the sea. The technology could help to monitor atmospheric precipitation better than before.

Scientists have shared early results from a trio of studies that aim to improve models designed to guide agricultural practices for reducing the risk of nitrogen and phosphorous farm runoff. Such runoff leads to the growth of toxic algae in waterways.

An increase in snowfall accumulation over Antarctica during the 20th century mitigated sea level rise by 0.4 inches. However, Antarctica's additional ice mass gained from snowfall makes up for just about a third of its current ice loss.

More and more rainfall extremes are observed in regions around the globe -- triggering both wet and dry records, a new study shows. Yet there are big differences between regions: The central and Eastern US, northern Europe and northern Asia have experienced heavy rainfall events that have led to severe floods in recent past. In contrast, most African regions have seen an increased frequency of months with a lack of rain.

Researchers mapped the changes in snow mass from 1982 to 2016 onto a grid of squares 2.5-miles on a side over the entire contiguous U.S. Grid size for previous studies was about 40 miles on a side. Since 1982, some parts of the West have a 41 percent reduction in the yearly maximum mass of snow.

NOAA's annual report card on the Arctic, released today, shows that the Arctic region experienced the second-warmest air temperatures ever recorded; the second-lowest overall sea-ice coverage; lowest recorded winter ice in the Bering Sea; and earlier plankton blooms due to early melting of sea ice in the Bering Sea.

Under future climate scenarios, changing winds may make it harder for North American birds to migrate southward in the autumn, but make it easier for them to come back north in the spring. Researchers came to this conclusion using data from 143 weather radar stations to estimate the altitude, density, and direction birds took during spring and autumn migrations over several years.

The future of the world's coral reefs is uncertain, as the impact of global heating continues to escalate. However, according to a new study, the response of the Great Barrier Reef to extreme temperatures in 2017 was markedly different to one year earlier, following two back-to-back bouts of coral bleaching.

Atmospheric scientists have documented a rare firenado, finding a number of factors that combined at just the right time and place to catalyze the deadly Carr Fire in Northern California. These observations may help forecasters and scientists identify -- and potentially warn - for future destructive fire-generated vortices.

Researchers examined how 18 years of drought affect the billions of vital bacteria that are hidden in the soil beneath our feet. The results show that this type of extreme weather determines how soils respond to future climate change.

A prediction lead time of about 2 to 5 weeks is sorely lacking in current forecasting capabilities for severe weather. Atmospheric scientists now demonstrate the ability to make skillful predictions of severe weather across the Plains and southeastern United States, including hail and tornadoes, in that coveted ''subseasonal'' time scale. To do it, they use a reliable tropical weather pattern called the Madden-Julian Oscillation, which can influence weather in distant parts of the Earth.

A new federal report finds that climate change is affecting the natural environment, agriculture, energy production and use, land and water resources, transportation, and human health and welfare across the U.S. and its territories.

Currently, half of the world's measured precipitation that falls in a year falls in just 12 days, according to a new analysis of data collected at weather stations across the globe. By century's end, climate models project that this lopsided distribution of rain and snow is likely to become even more skewed, with half of annual precipitation falling in 11 days.

New supercomputer simulations by climate scientists have shown that climate change intensified the amount of rainfall in recent hurricanes such as Katrina, Irma, and Maria by 5 to 10 percent. They further found that if those hurricanes were to occur in a future world that is warmer than present, those storms would have even more rainfall and stronger winds.

Researchers found that Houston's urban landscape directly contributed to the torrential rainfall and deadly flooding of Hurricane Harvey in 2017. Houston's risk for extreme flooding was 21 times greater due to urbanization. The results highlight the human role in extreme weather events and the need to consider urban and suburban development when calculating hurricane risk.

Milder winter weather increased regional crime rates in the United States over the past several decades, according to new research that suggests crime is related to temperature's effect on daily activities.

As an indicator of the impacts of climate change, Arctic sea ice is hard to beat. Scientists have observed the frozen polar ocean advance and retreat at this most sensitive region of the Earth over decades for insight on the potential ripple effects on assorted natural systems: global ocean circulation, surrounding habitats and ecosystems, food sources, sea levels and more.

Researchers have evidence that Kawasaki Disease (KD) does not have a single cause. By studying weather patterns and geographical distributions of patients in San Diego, the research team determined that this inflammatory disease likely has multiple environmental triggers influenced by a combination of temperature, precipitation and wind patterns.

New research identifies areas of the UK which could rival the Champagne region of France. Climate and viticulture experts identified nearly 35,000 hectares of prime viticultural land for new and expanding vineyards -- much of it in Kent, Sussex and East Anglia. As climate change drives warmer growing season temperatures in England and Wales, this new viticulture suitability model allows, for the first time, an objective and informed rapid assessment of land at local, regional and national scales.

Even a Category 4 hurricane doesn't kill the mood for coastal fish -- and that's good news for all species, as well as for a multibillion-dollar recreational fishing industry. As extreme weather patterns threaten to bring more and larger storms to the Gulf Coast, new findings show some important fish species are able to continue spawning even in a severe storm.

One concern with the increase vessel transits in the western Canadian Arctic is how noise pollution can detrimentally affect marine animals. Researchers have found that the negative impact of noise from shipping vessels can be mitigated by reducing the ship's speed.

Continued burning of fossil fuels is likely to fuel even more extreme summers than that of 2018 because of its impact on the jet stream. The rapid disappearance of aerosols produced by pollution may, however, mitigate the impact until mid-century if countries like China phase out these fuels, according to scientists using climate models to predict changes in the occurrence of so-called Quasi-Resonant Amplification (QRA) events associated with persistent weather extremes.

Researchers studying the sharp decline between 1980 and 2010 in documented landings of the four most commercially-important bivalve mollusks -- eastern oysters, northern quahogs, softshell clams and northern bay scallops -- have identified the causes. Warming ocean temperatures associated with a positive shift in the North Atlantic Oscillation (NAO), which led to habitat degradation including increased predation, are the key reasons for the decline of these four species in estuaries and bays from Maine to North Carolina.

Larger tropical stingless bees fly better in hot conditions than smaller bees do and larger size may help certain species better tolerate high body temperatures. The findings run contrary to the temperature-size 'rule,' which suggests that insects that rely on the external environment to control their temperature are larger in cold climates and smaller in hot ones.

An annual model-based report on low-oxygen conditions in Chesapeake Bay during 2018 indicates a total volume of 'hypoxic' waters very similar to the previous year, but with a dramatic drop in hypoxia during late July due to mixing by strong winds. The duration of hypoxia in 2018 was greater than in recent years.

Researchers have demonstrated for the first time that runoff extremes have been dramatically increasing in response to climate and human-induced changes. Their findings show a large increase in both precipitation and runoff extremes driven by both human activity and climate change. They also found that storm runoff has a stronger response than precipitation to human-induced changes (climate change, land-use land-cover changes, etc).

The fall of Angkor has long puzzled historians, archaeologists and scientists, but now a research team is one step closer to discovering what led to the city's demise -- and it comes with a warning for modern urban communities.

We live in an age of long-range information. Research is turning towards the use of lasers which have several advantages. However, this new technology faces a major problem: clouds. Due to their density, clouds stop the laser beams and scramble the transfer of information. Researchers have now devised an ultra-hot laser that creates a temporary hole in the cloud, which lets the laser beam containing the information pass through.

School students have successfully identified sounds caused by a solar storm in the Earth's magnetic shield. The group of students identified a series of waves whose pitch decreased over the course of several days. They found that this event occurred after a Coronal Mass Ejection or 'solar storm' caused a great disturbance to Earth's space environment.

Winds blowing across snow dunes on Antarctica's Ross Ice Shelf cause the massive ice slab's surface to vibrate, producing a near-constant set of seismic 'tones' scientists could potentially use to monitor changes in the ice shelf from afar, according to new research.

El Niño-Southern Oscillation (ENSO) leads to extreme climatic variations called El Niño and La Niña that cause dangerous weather conditions in many regions throughout the world. Currently, a reliable forecast of the ENSO phases can be made about a year beforehand. This study details a novel method that allows for the accurate forecast of its phases up to 17 months in advance.

Hurricane Michael plowed into the Florida panhandle Wednesday, Oct. 10, as a major Category 4 storm -- the strongest hurricane ever to hit that region. Many NASA instruments are keeping tabs on Michael from space.

Global warming is projected to spawn more extreme wet and dry weather around the world, according to a new study. Those extremes include more frequent dry spells in the northwestern, central and southern United States and in Mexico, and more frequent heavy rainfall events in south Asia, the Indochinese Peninsula and southern China.

Due to climate change, springtime growth begins earlier each year. Up to now, it was thought that this phenomenon was slowing climate change. However, as evaluations of satellite data have now shown, the opposite is the case.

Anthropogenic warming will increase the burned areas due fires in Mediterranean Europe, and the increase of the burned area could be reduced by limiting global warming to 1.5ºC. The higher the warming level is, the larger the increase of the burned area is.

Severe weather events, such as summer hurricanes, tornadoes, and winter snow storms often result in widespread and prolonged power outages, interrupting essential household functions, including home heating. An emergency medicine physician addresses the risk of carbon monoxide poisoning associated with furnaces and generators used in such conditions.

Persistent weather conditions, including dry and wet spells, generally have increased in the United States, perhaps due to rapid Arctic warming, according to a new study. Persistent weather conditions can lead to weather extremes such as drought, heat waves, prolonged cold and storms that can cost millions of dollars in damage and disrupt societies and ecosystems, the study says.

A new study suggests the power industry is underestimating how climate change could affect the long-term demand for electricity in the United States. The research describes the limitations of prediction models used by electricity providers and regulators for medium- and long-term energy forecasting. It outlines a new model that includes key climate predictors that researchers say present a more accurate view of how climate change will alter future electricity demands.

Human-caused climate change has exposed US national parks to conditions hotter and drier than the rest of the nation, says a new study quantifying for the first time the magnitude of climate change on all 417 parks in the system. Without action to limit greenhouse gas emissions, many small mammals and plants may be brought to the brink of extinction by the end of the century, the study shows.

Scientists have found that additional weather observations in the Arctic can help predict the track and intensity of tropical and mid-latitude cyclones more accurately, improving weather forecasting of extreme weather events.

Researchers report that forests with trees that employ a high diversity of traits related to water use suffer less of an impact from drought. The results, which expand on previous work that looked at individual tree species' resilience based on hydraulic traits, lead to new research directions on forest resilience and inform forest managers working to rebuild forests after logging or wildfire.

Scientists have observed for years that Earth's tropics are widening in connection with complex changes in climate and weather patterns. But in recent years, it appeared the widening was outpacing what models predicted, suggesting other factors were at work. But a new paper finds that the most up-to-date models and the best data match up reasonably well.

Using cloud computing and data from 143 weather radar stations across the continental United States, researchers can now estimate how many birds migrate through the US and the toll that winter and these nocturnal journeys take.

September is the peak of autumn bird migration, and billions of birds are winging their way south. Using a combination of artificial intelligence and weather forecasting can help scientists to predict the movements of millions of birds and support their conservation goals, according to new research.
